Improvement in vehicle-gearing



w 4 STATES v MPRORVEIMENTIIN Specification formingipart of LettersPatent N0. 187,69 l, dated February 20, 1877; application filed 4September 30, 1876.

To all whom it may concern: Be it known that I, DAVID G. WYETH, of

of Ohio, have invented a new and Improved Vehicle-Gearing and I dohereby declare that the following is a full, clear, and exactdescription of the same.

The object of this invention is to provide a vehicle-gearing in which areach, fifth-wheel, antdh ordinary form of bolster are dispensed W1 Thesprings are coupled in pairs, and arranged in a triangular relation tothe rear axle. The front bearings of the springs are also constructed ina peculiar manner, as here inafter fully described.

In the accompanying drawing, forming part of this specification, Figure1 is a side view of my improved gearing. Fig. 2 is a bottom plan view.Fig. 3' is a cross-section on line 00 w of Fig. 1. Fig. 4 is a rear viewof the front bearing or fifth-wheel. Fig. 5 is a detail view, showingthe means (clip and clip-plate) for connecting the springs of each pairto the rear axle.

A A indicate two pairs of half, or semielliptical, leaf-springs, theindividual springs of each pair being arranged parallel in a verticalplane, and the respective pairs being attached to the rear axle, nearthe journals thereof, and their'front ends converging to' the point ofconnection with the front axle. In other words, the pairs of springs andthe rear axle are so arranged as to form a triangle. The springs of eachpair are separated at the center by means of blocks 0, which serve toprevent rolling of the axles. The body D of the vehicle is secured tothe upper springs by means of braces E, having the form of a scalenetriangle. These braces are attached to the springs by clips at andabolt, b, which passes through the springs, block, brace, and

sills of the wagon-body, as shown. The lapped inner ends of thetriangular braces E are secured by a single bolt, 0. The braces serve toprevent rocking of the body-D when one of the hind wheels encounters aresistance, and they also rigidly connect the pairs of springs, so thatthey are held always in the same triangular relation to the rear axle-The springs bracesc'f New Way, in the county of Licking and State Amalso stayed laterally by transverse In order to provide a .spacebetweenthe front axle and the front end of the body D, which will allow bumpingroom, or for the movement of that portion of the body up and down, Iattach the body to the springs at a point in rear of their lengthwisemiddle. I

make their rear portions stiffer, to enable them to support theadditional weight thus imposed on them.

The ends of all the springs are finished the same, and so fitted intheir sockets in clips of rear axles and the ends of front bearers H H,that they bear on'the lower side of said socket-s, as well as on thepivot-bolts, thus takin g part of the strain and wear off the bolts. Therear ends of the upper springs are socketed in clips I and the lowersprings in clipplates K. The arms 0 of these clips extend down on eachside of the axle, through perforated ears of the clip-plates, and aresuitably secured together by cross-pins nuts, or other devices. Theclips and clip-plates thus constitute a socket for the axle.

The substitute which I employ for the ordinary fifth-wheel isconstructed in part upon the principle of the bearing for which Iobtained Letters Patent No. 176,415. In this instance the bearing isextended laterally, forming a curved bar, H, in ,whose ends are thesockets of the upper springs A. The hearing for the lower springs is acurved bar, H, similarly provided with sockets in its ends. Half of thesocket g, for the circular dovetailed or beveled portion h of thebearing, is formed or cast in one piece with the lower bar H, as shownin Fig. 3, and the other part of said socket is a detachable piece, t,Fig. 2. The ends of bars H H are bent, respectively, downward andupward, or toward the axles,

and also curved forward in a horizontal plane,

so that the axis of each socket formed in the ends of the bars H H maybe in a line at right angles to the spring whose end rests in it, and sothat the pressure and resistance, both vertically and laterally, shallbe in a straight line, passing through the center of the part h. Thepressure and resistance are, therefore, in the same vertical plane asrespects both bars H and ,H and the springs socketed therein, and thereis no unequal or side twist or torsion, and hence no unequal frictionand Wear of the bearing proper. The respective bearers H and vH have aprojection, l, on the under side of which an annular groove, m, Fig.4,is formed to prevent water entering the joint of the coupling. Thebolt n, Fig. 4, passes transversely through the front axle and throughthe lapped portion of the clip-connections at that point.

What I claim is v v 1. The triangular braces E and the blocks 0, incombination with the pairs of springs and body of a vehicle,substantially as shown and described.

2. The upper and lower bearers H H, the clips I and K, and the two pairsof springs A, arranged in a triangular relation to the rear 'axle, allcombined as shown and described,

whereby the upper and lower springs of each pair are connected to theaxles, respectively, above and below the latter, as and for the purposespecified.

3. The front bearers H and H, curved as shown and described, andprovided with sockets having pivot-bolts, arranged diagonally, as andfor the purpose specified.
